JESSE. T. GLYMER,

OF GALION, OHIO.

Letters Patent No. 94,398, dated August 31, 1869; antedated August 25,1869.

To all whom it may concern Be it known that I, J nssn T. GLYMER, ofGalion, in the county of Crawford, and State of Ohio, have inventedcertain new and useful Improvements in Stove-Pipe Drums; and I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawing, and to theletters of reference marked thereon, making part of'this specification,in which- Figure l is'an exterior view of the drum.

Figure 2 is a vertical sectional view.

Figure 3 is an outline of the upper cone, showing the arrangement ofventilators therein.

The object of my invention is to construct a neat and ornamental drum,so arranged that the draught can readily be regulated, the degree ofheat greatly augmented, the accumulation of soot, ashes, and all otherimpurities in the pipe or drum, securely guarded against, and allaccomplished in asimple, substantial, and practical manner, and with thegreatest saving and economizing of fuel.

The great objection to the drums now in use is found in the difficultyexperienced in gaining access to the interior of the same, which isoften not only desirable, but absolutely necessary, for the purpose ofcleaning and repairing.

This ditiiculty arises from the fact that the entire outer casingconsists of one close cylinder.

I construct my drum in two sections, each section being conical in form,and united attheir base by means of aflange on the one, which fitsclosely over the other, forming a perfectly tight joint or connection.

While, by this arrangement, all danger of the escape of smoke, soot, andother impurities, is securely guarded against, it, at the same time,affords the.

greatest facility of access for the purposes of cleaning and repairing.

The form of the drum-the double cone-possesses many advantages overthose whose diameter is uniform throughout.

It is also cheaper, more ornamental, occupies less space, and stillaffords all the surface necessary for the radiation of the heat that isdesirable or requisite.

My invention consists in the peculiar arrangement of the interiorradiating-cones or funnels, do two being oflikc-dimension.

The diameter of the upperv cone, at its base, is nearly as great as thatof the drum at the point at which the sections meet or are united, onlya small space being left between theouter line of its circumference andthe interior surface of the drum for the passage of smoke, &o., and asthe series descends in i the lower cinical section, and toward its apex,itnecessarily diminishes in size in order to conform to its angularslope.

Another great advantage of my invention consists in the arrangement ofthe cones or funnels on an upright axial rod.

In other drums, where cones or funnels are used for radiating-purposes,they are never sustained by independent or removable bearings, but areinvariably supported by means of flanges, metal strips or strapsattached to the same, and also to the interior of .the' drum.

A moments reflection will clearly show the disadvantages of such anarrangement, as well as the superiority of mine over the same.

-In the drums alluded to, should you desire, for any purpose, to removethe lower funnel, (and, owingto the greater intensity of heat to whichit is subjected, it always burns out before the others,) you cannot gainaccess toit without removing the entire series; and each being united bythree or four metallic strips to the interior of the drum, the .laborand diliiculty of so doing are far. from incousiderable.

By my arrangement, you have only to disconnect the sections of the drumand lift the axial rod out of its hearing or step, and you have theutmost freedom of access to the entire series ,of cones or funnels, oreither one of the same desired.

In my arrangement, the upper cone is fastened to the rod by a pin, andthe lower one is supported by metallic straps or hands, hanging from theupper cone; those that are intermediate fitting in loops formed in thesame.

The axial rod is stepped in a plate arranged at the apex of the lower'c'one, and is held in position by means of a collar or shoulderarranged or cast on the same.

The upper end of the rod is held securely in a plate or bar arranged inthe upper section of the drum.

Another great advantage of my invention consists in the airangement ofthe damper and valve, and the means of operating the same, whereby thedegree of heat is successfully controlled, and the amountof airadmitted, readily regulated.

The ordinary plate-damper, secured to a movable or stationary rod,having permanent hearings in the,

pipe or drum, furnishes no feature of my invention.

Many methods have been essayed to render such a damper successful,especially in drums, but with indifferent success; among the mostpopular of which, theoretically, and, indeed, until their defects werediscovered by use' and practical'experience as to their working, werethose that operated automatically, commonly known as the thermostaldampers. These are usually operated in the following manner:

To the damper-plate is hinged, or otherwise 'at-. tached, a compoundlever. I l

The end of the lever, rests on or is connected with one orimore bars orplates of expansive metal, arranged within the pipe or drum, and runningparallel with the sides of the same.

The slightest elongation orcontra'ction of .the metal necessarily movesthe damper, and consequently opens or closes the passage for the air.

This method is perfectly arbitrary in operation, leaving you, inreality, no control over the damper.

Should you attempt to retain the damper at any desired point by means ofa thumb-screw, or equivalent device, the metal bar cannot be preventedfromexpanding, and consequently will soon become bent; its bow-form so,weakening it as to render the same entirely worthless.

vMy arrangement is free from all such defects.

In the upper end of the drum, and to' the walls of the same, 1permanently secure an inverted frnstum of a cone, with an aperture atits apex.

Around this aperture or opening is arranged a valve-seat, in which fitsand works a foraminated valve; i

This valve is in no manner connected with the walls or sides ofthe'drum, but depends for its entire support on a short upright rod, towhich it is permanently attached.

This rod is hinged to a bent lever, which projects through an opening inthe side of the drum, and sufficiently far beyond the same to furnish'afulcrum, on which works a short curved lever, which in turn is operatedby a rod and thumb-screw, arranged in a suitable casing on the outsideof the drum.

By this arrangement of levers and rods the valve is raised and lowered,and consequently the degree of draught regulated-at pleasure.

My invention also consists in arranging in two circular necks, by meansof which the drum is attached.

to the stove-pipe, ventilators. 7 These ventilators are for the purposeof admitting cold air to the drum.

The upper one also serves to .remove foul-air from the apartment.

The lower one is also a great aid in regulating the heat in the drum,which may be done by shutting the stove-damper and opening theventilator..

The whole device is simple and of little cost, and can be attached toand used with any form of cook-- ing or heating-stove, increasing theradiation of heat therefrom and diminishing the consumption of fuel to avery great degree.

To enable othersskilled in-the art to make and use my invention, I willnow proceed, to describe its construction and operation.

The drum is composed of two cylinders or sections,

A and A, each conical in form.

The section A is formed .with a flange, a, which fits closely over thebase of the-section A, so that when the two are united,.a perfectlytight joint is formed, and the escape of smoke, soot, &c., securelyguarded against.

Theedge of the flange a may be serrated or otherwise ornamented, to suitthe fancy of the manufacturer or purchaser.

The apex of each of the sections, A and A, is open, and connected withshort circular cylinders or necks, B and B, and by means of which thedrum is attached to the stove-pipe.

The neck B is provided with a ventilator, N,and the neck B with aventilator, 0.

-These ventilators, N and 0, are provided with valves a-and o, by meansof which they are opened and closed at pleasure, and through theiragencycool air is admitted to the drum, the lower ventilator 0increasing the heat when the damper is closed, and the ventilator Ncarrying off all the impure air in the apartment.

O is a metallic plate, extending across the lower portion of the sectionA, and serves as a step or seat by means of .a' collar or shoulder, 'i,as clearly shown in fig. 2.

The upper end of the rod D is retained in position by means of anopening in the plate 0', which is supported by the valve-cone F.

To the axial rod D are attached several inverted cones, E E E Thesecones are tapering in size, in order to conform to the interiordimensions of the'druln, their diameters being such as to leave a.narrow passage for the air between the same and the drum;

The uppercone E is fastened to the rod by means of a pin or bolt, m.

'To the under surface of the cone E are soldered straps, 'r'r.

These straps are firmly secured to and support the lower cone E, whilethe cone E enters and is supported by loops, 1" r, arranged midwaythestrap or band.

Thus. it will be seen that the entire support of the cones or funnelsdepends on the axial rod D, they drum.

"The cone E is made of iron or other hard metal, while the others are oftin.

This diifererrce of material is in consequence of the greater intensityof heat to which 'the cone E is subjected.

Near the upper end of the section A, and to the interior walls of thesame, is firmly secured an inveited cone, F, whose apex is left open.

Around this opening is a valve-seat, in which rests the valve G.

shown in fig. 2 servesefl'ectually to check the draught upward throughthe opening in thecone 1*.

rod, H, which is hinged to the bent lever I.

an opening in the section A toafl'ord a fulcrum for the curved cam-leverJ to work upon.

This lever J is, connected with a rod, K, which is provided with athumb-screw, L.

This rod K is arranged and works within a metallic casing, m, secured tothe outside of the drum.

By turning the thumb-screw L, the rod K is drawn the bent lever I,elevates the hinged or jointed end quently, the valveG, which enlargesthe passage for smoke, 85c. Then, by simply turning the thumbsc'rew L inthe opposite direction, you free the bent lever I from the pressure ofthe lever J, which instantly permits the valve to fall in its. seat andoccupy the position clearly shown' in fig. 2 of thedrawing.

I am aware that cones have been used, so arranged that by means ofratchet-bars and pinion-wheels, the same can be moved in a verticaldirection, and thus caused to act as dampers.

This arrangement difi'ers entirely, from mine, for my series of conesare firmly connected together and so supported on an axial rod by meansof a single pin, that when the drum is in operation, the entire seriesare heldstationary, the rod resting insuitable bearings. I
